Processing Just Stopped!??

2/3 of the way into processing 6K images, and POOF, everything stopped! Figuring from reading other issues, tried to delete some galleries (just in case), and nothing happens except "wheels turning", like "no response". Is that likely an issue with my server or Photocart??

Never had the issue before. I do event photography, and have uploaded several events over the past few years with more than 8K images. 4-6K is common. But, it wouldn't surprise me if my ISP "f'ed" it up for me. Restarted "processing" this morning, and it's working, but crawling!!! Did a connection speed test, it's up to speed, but damn it man, at this rate, it'll take 20hrs to process this batch. Rarely ever taken more than 6-8hrs. Shit that makes you go Hmmmmm? lol

Oh Tim, do tell me how to "restart"!! lol. I couldn't figure it out, and restarted from scratch! It seems to be taking much longer today than ever before, and we're using the dame process we've used for a few years now. After this, I think I'll be looking into to alternatives though. I like everything about photocart, and not really seeing Sytist as an answer to what and how we do things. At this point, it has processed just over 2100 images in 7.5 hours. Each file is about 6MB. Again, we've done it this way from the start. I may go to a smaller file size after our next event and just inconvenience the customer when they want a larger digital file.
If you can show me where Sytist can create many sub galleries within galleries, and display file names (numbers), I'm not opposed to trying it. Just not seeing that in the demos.

"starting over" wasn't an option!!!! The tab that normally says "process images" was not available, and I couldn't find an alternative, So, I'm sitting here 15hrs later with only 4400 images processed!!!!!!!!!!!!!!!!!!!! lol. You can bet your ass, I'll find another way of doing this!! My paid help didn't give a shit, because he was drawing a check! I care!
